CALL-BELL.

SPEGIFIQATION forming part of Letters Patent No. 277,741, dated May 15, 1883.

' Application filed January 11,1883. (No model.)

To all whom tt may concern.- v

Be it known that I, AUGUSTUS H. JoNEs, of Meriden, in the county of New Haven and State of Connecticut, haveinvented a new Improvement in (JaltBells; and I do hereby declare the following, when taken in connection with accompanying; drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure l,a sectional side view; Fig. 2, transverse section through the stud on the line where the hammer is hung.

This invention relates to an improvement in that class of call-bells in which the bell is arranged upon a post, with a spindle loose the hammer hung to the post within the bell, and an arm extending beneath the spindle, and so that pressure upon the spindle will throw the hammer' against the hell. The hammer, swinging freely, returns the spindleby its own weight.

In the usual construction of this class of bells the upper end of the post is cast with two ears, between which the hammer is hung. The cars are drilled, as well as the end of the hammer shank, and through the ears and shank a pivot is introduced, and riveted on opposite sides of the cars. It is difficult to drill the ears so perfectly that the hammer will hang free and easy, which it is necessary it should do in order that it may return after having been forced against the bell, and in so returning lift the spindle. In some cases the post has been cast with a seat or loop, and the hammer constructed tohang thereon, held in its place by the bell. It.frequently occurs in this last construction that the not or collar, which is screwed down on top of the bell to hold it upon its seat on the post, becomes loosened suiiiciently to permit the hammer to jump from its seat, and any person not familiar with the construction of the bell has difficulty in replacing the hammer, so that a permanentlyattached hammer is preferable. v

The object of my invention is to overcome the ditliculties existing in the old method of the two drilled ears and pivot, and yet make a permanent attachment of the hammer; and it consists in constructing the post with a single ear, correspondingly drillingthe single ear and hammer-shank and introducing a headed rivet through the hole in the shank, its end through the ear, and there riveted, as more fully hereinafter described.

A represents the base; B, the post on which the hell 0 is placed, and there secured by the tubular collar I), through which the spindle E operates, all in the usual manner. At the upper end of the post I cast a single car, a. Through this car I make a single hole, I), and through the shank of the hammer a hole, (1, of a little larger diameter than that in the can I then take the headed rivet, the body 8 of which corresponds to the hole through the shank, the head f slightly larger, the length of the body little more than the thickness of the hammer-shank, the opposite end of the rivet reduced to a diameter smaller than the body, and corresponding to the hole through the ear. This rivet is inserted through the shank and through the ear until the shoulder of the rivet comes upon that side of the ear next the hammer, then the outer end is riveted down, as seen in Fig. 2, which firmly secures the rivet to the ear and leaves the hammer free to swing on the stud thus formed. The arm Z extends from the hammer, as seen in Fig. 1, beneath the spindle, to be operated by pressure upon the spindle, in the usual manner.

By this construction perfect freedom of the hammer is insured, as well as a permanent attachment.

Another advantage in this construction is that the employment of a single ear facilitates the casting of the posts and avoids fitting the the hammer between the two cars.

It is well understood that the rivet or stud is swaged or made by machinery, so that all may be exactly alike, and not vary, as neces sarily must the spaces between the two ears in the usual construction.

I claim-- 'In a call bell substantially such as described, the post which supports the bell,conport the hammer on the rivet between its structed with 21 single ear, a, combined with head and the single ear, substantially as dethe hammer, the shank of which and the ear scribed.

are each constructed with a single hole, and AUGUSTUS H. JONES. a headed rivet introduced through the hole Witnesses: I in the shank of the hammer and through the t E. A. MERRIMAN,

hole in the single ear, and riveted to sup CHARLES W. MANN.
